Pampa Metals Provides Mobilization Update on Follow-Up Diamond Drill Testing of the Piuquenes Porphyry Copper-Gold Project

VANCOUVER, December 20, 2023 - Pampa Metals Corp. ("Pampa Metals" or the "Company") (CSE:PM)(FSE:FIR)(OTCQB:PMMCF) is pleased to advise that preparatory works for the follow-up diamond drill program designed to test the depth and lateral extension of known mineralization at Piuquenes are advancing, with camp setup and platform preparation nearing completion.

Drilling is scheduled to commence in mid-January 2024, with assay results to follow shortly thereafter.

Piuquenes Porphyry Copper-Gold Project

In November 2023, Pampa Metals assayed and re-logged Anglo-American's 2016 diamond borehole of 920.2 m length which had crossed the mineral zones previously drilled by Inmet Mining Corp. (IMC). These results were reported in a 5 December 2023 News Release and included:

- 558.2 m (362-920.2 m EOH) @ 0.38% Cu & 0.42 g/ Au & 2.4 g/t Ag (0.73% CuEq)*
Including:
- 130 m (362-492 m) @ 0.81% Cu & 0.6 g/t Au & 4 g/t Ag (1.31 % CuEq)*;
- 180 m (362-542 m) @ 0.71% Cu & 0.61 g/t Au & 3.8 g/t Ag (1.22% CuEq)*; and
- 296 m (362-658 m) @ 0.5 % Cu & 0.5 g/t Au & 2.7 g/t Ag (0.91% CuEq)*,

Historically, IMC (subsequently acquired by First Quantum in 2013) intersected significant copper and gold mineralization at Piuquenes (refer 30 November 2023 News Release) including:
• 413.5 m (167-580.5 m) @ 0.47% Cu and 0.52 g/t Au (0.87% CuEq)*;
• 67.5 m (207-274.5 m) @ 0.63% Cu and 0.51 g/t Au (1.02% CuEq)*; and
• 158 m (3-161 m) @ 0.32% Cu and 0.6 g/t Au (0.78% CuEq)*.

* %CuEq values are calculated based on copper and gold metal prices: Cu = US$3.20/lb, Au = US$1,700/oz and Ag = US$ 20/oz. The formula utilized to calculate %CuEq is: Cu Eq Grade (%) = Cu Head Grade (%) + [(Au Head Grade (g/t) / 31.104) * (Au Price (US$/oz) / Cu Price (US$/lb) / 22.04) + [(Ag Head Grade (g/t) / 31.104) * (Ag Price (US$/oz) / Cu Price (US$/lb) / 22.0.
